Step-by-step explanation: I did this in school and got it right.
Answer is a right triangle. The angles of a triangle must add to 180 degrees.
You have two 45 degree angles
45 + 45= 90
Now you need 1 more angle to equal 180
180- 90= 90
A right angle is 90 degrees. A right triangle has one right angle and two acute.

Second number =49
Step-by-step explanation:
Question:
The sum of two numbers is 75. The second number is 3 less than twice the first. Find the numbers.
Given:
Sum of two numbers = 75
The second number is 3 less than twice the first.
To find the numbers.
Solution:
Let the first number be = 
Let second number be = 
The sum equation can be given as:

It is given that the second number is 3 less than twice the first.
This can be given as:

Substituting the value of
in terms of
in the sum equation.

Combining like terms.

Adding 3 both sides.


Dividing both ides by 3.


Substitution
in the second equation to find
.

Thus, first number =26 and second number =49.
